P600 Methods for Testing the Performance of LEV

P600 Methods for Testing Performance of LEV

A one-day P600 LEV course delivered as a Webinar (‘live’ using Zoom) or face-to-face (Leicester Hilton Hotel)

At checkout – there is no need to pay at that stage.  We will send out Invoices approx 5-6 weeks prior to the course start date.

The course enables delegates to identify and correctly use appropriate LEV flow-visualisation and measurement techniques (LEV Test Instruments) to test the performance of Local Exhaust Ventilation (LEV) systems ….. under supervision.

The focus is on the fundamentals of LEV systems; standard components parts, measurementand testing techniques etc.

This course provides delegates with the necessary skills and knowledge to progress their career in LEV.

In general terms – delegates will gain knowledge and experience of:-

  • Basic components of local exhaust ventilation systems.
  • Qualitative visualisation techniques (smoke release/’dust lamp’ etc).
  • Quantitative measurement techniques (anemometers, Pitot tubes etc).


Delegates wishing to attend P600Methods for Testing the Performance of LEV” Webinar/On-Line training course are expected to have some basic knowledge of LEV systems.

Who should attend?

Anyone responsible for operating or maintaining LEV systems as part of their work.  This includes – for example – engineers, managers, supervisors, equipment designers, service engineers, technical sales staff and LEV technicians etc.

It is a very useful and practical training course for anyone who requires a foundation level of understanding of LEV systems in order to progress to a Level 4 qualification P601P604 series).  P600 is a Level 3 course.

The P600 qualification may also meet some of the base requirements towards membership at the Society of Operations Engineers (SOE) and the Institute of LEV Engineers (ILEVE).

P600 LEV Course programme

Webinar/On-Line or Face-to-Face Presentation

  • Introduction to the basic components of local exhaust ventilation (LEV) systems (i.e. inlets, ductwork, air cleaners, air movers, ventilation hoods and discharges)
  • Demonstrate the use of smoke generators and/or smoke tubes to visualise air flows in and around LEV systems
  • Use of a dust lamp to visualise fine airborne dust
  • Using a pitot tube/manometer combination
  • How to carry out a Pitot tube traverse to determine static pressure (Sp), velocity pressure (Vp), and then calculate the velocity in a ducted ventilation system
  • Principle of operation of vane and hot wire anemometers
  • How and where to undertake measurements in relation to the inlets (hoods etc) of an LEV system
  • Chosing the correct test equipment to use and how to use them correctly


At the end of the day there will be a short Multiple Choice Questionnaire (MCQ) examination comprising of 20 questions (time allowed 60 mins).  The exam will be marked by BOHS and on satisfactory conclusion of the MCQ, BOHS will award a “P600 Course Certificate“.


£295 (+exam fee £65) + VAT / delegate

Follow-on course

The P601 Thorough Examination & Testing of LEV Systems course is a natural follow-on from this course, as is the OXYL8 P602 LEV Design Training Course.

Success with OXYL8

We work very hard with all our students to try and ensure a pass ….. first time.  To assist we have comprehensive course materials and handouts, pre-course guides and support.  Our pass rate is excellent!

Customer Reviews

“Bill I must thank you for a very enjoyable LEV course. I have to say that, the way you developed the information was first class – the delivery was fluent, natural – in fact it came across as extemporaneous! It was also very informative about the subject so as to enable us to undertake the practical aspects out on site. I don’t profess to be an expert in such matters – but I thought it was very well done and it’s no surprise that your pass rate is high. ( I just hope to be in that statistic!)”

“I would like to give Bill Cassells a huge shout-out. Absolutely fantastic Tutor with more knowledge in LEV training than anyone I have ever met. Just received my LEV certificates today in both P601 and P602. Without the help of Bill this probably wouldn’t have happened. Anybody thinking on doing these LEV courses, look no further than this Man. I will hopefully be doing the P604 Course at some point also.”
